The present study proposes and demonstrates the polarization-sensitive low-coherence interferometry (PS-LCI) technique combined with polarization-based transmission studies for characterizing chicken sciatic nerve fibers and tendons. A supercontinuum source with optical filters with broadband transmission characteristics around the wavelength region of 1060 and 1300\u00a0nm. The spectral information of both polarization states confirmed the birefringence characteristics of the nerve fiber bundle and tendon tissue. The retardance values estimated using the polarization-based transmission measurements show that the refractive index difference, \u0394\n                    <jats:italic>n<\/jats:italic>\n                    , between the nerve fiber bundle with an overall thickness of \u22481mm and that of the tendon tissue bundle with an overall thickness of \u22481.2mm was \u22480.6\u00d710\n                    <jats:sup>\u22124<\/jats:sup>\n                    . The PS-LCI-based birefringence measurements of the sciatic nerve fiber bundle and tendon bundle show \u0394\n                    <jats:italic>n<\/jats:italic>\n                    \u22481.0\u00d710\n                    <jats:sup>\u22124<\/jats:sup>\n                    .
